Structure of hollow floor

The invention relates to a false floor construction for residential and business premises. The invention can be preferably used in the reconstruction of old buildings. The invention aims at providing a false floor construction absorbing all forces, that can easily adapt to different building height requirements while considering the required footstep noise and heat insulation, whereby the surface of the false floor can be built in any material. This is achieved by a false floor construction comprising floor elements consisting of a multilayered composite material shaped as plates and supported on the bare structural floor, whereby one of the layers is configured as a flexible core layer. The floor elements are formed by two flat steel plates (51, 52) which are preferably similar and which are arranged at a defined distance in relation to each other. The steel plates (51, 52) are fitted with circular recesses arranged in a grid, all of which have the same diameter. Threaded bolts (6) are inserted in the coaxial recesses at an appropriate distance, said bolts being rotationally supported on the bare floor. The hollow space between the steel plates (51, 52) is filled with a hardening flowing material which is applied after said plates have been mounted and leveled.
